What to Expect During a DEXA Bone Density Scan?
Bone health is something many of us don’t think about until a problem arises. A DEXA bone density scan is one of the most accurate ways to assess bone strength and the risk of
fractures, especially for conditions like osteoporosis. At ImageCare Radiology, we strive to make the experience as comfortable and stress-free as possible. Here’s what you can expect before, during, and after your scan.
What Is a DEXA Bone Density Scan?
DEXA stands for Dual-Energy X-ray Absorptiometry. It’s a type of medical imaging that uses low-dose X-rays to measure the density of your bones, most often in the hips and spine. The scan is quick, painless, and provides important information your doctor can use to evaluate your bone health and guide treatment if needed.
How to Prepare for Your Scan
Preparing for a DEXA bone density scan is simple. In most cases, no special diet or fasting is required. A few guidelines will help your visit go smoothly:
- Clothing: Wear comfortable clothes without zippers, buttons, or metal fasteners if possible.
- Supplements: Avoid calcium supplements for 24 hours before your appointment.
- Recent Imaging: Let your technologist know if you’ve had a barium study, CT scan with contrast, or nuclear medicine study in the past week, as these can interfere with results.
- Pregnancy: Inform the technologist if you may be pregnant, as radiation exposure should be avoided.
What Happens During the Exam
When you arrive at ImageCare Radiology, our friendly staff will guide you every step of the way. The exam itself is simple:
- Positioning: You’ll lie flat on a cushioned exam table. A scanning arm will slowly move over your body, taking images of the targeted areas, usually the hip and spine.
- Comfort: The scan is completely painless. You don’t need to go inside a tunnel or receive an injection. All you need to do is remain still while the images are taken.
- Time: Most scans take about 10–20 minutes from start to finish.
After Your Scan
There’s no recovery time required. You can return to your normal daily activities immediately after the exam. A radiologist will carefully analyze your results and send a detailed report to your doctor. Together, you’ll review your bone density score and discuss next steps, whether that’s maintaining your current bone health or considering treatment options.
Why a DEXA Scan Matters
Bone health plays a major role in staying active and independent as we age. A DEXA scan can:
- Detect early bone loss before a fracture occurs
- Monitor changes in bone density over time
- Help guide treatment decisions for osteoporosis
- Provide peace of mind when your bones are strong and healthy

With just a short, painless test, you gain valuable insight into your bone health and take an important step toward protecting your future well-being.
FAQ: DEXA Bone Density Scan
Is a DEXA scan safe?
Yes. DEXA uses very low levels of radiation, much less than a standard chest X-ray, making it a safe option for most patients.
How often should I have a DEXA scan?
Your doctor will recommend the frequency based on your age, bone health, and risk factors. Typically, scans are done every 1–2 years for those at higher risk.
Does it hurt?
No. The scan is painless, and you simply lie still while the images are taken.
How quickly will I get my results?
Your radiologist reviews the images and sends a report to your doctor, who will discuss the results with you—usually within a few days.
